-From d6f9b4eb74f8be1be90ee315ed3895e6b0265c42 Mon Sep 17 00:00:00 2001

-Subject: [RFC 01/12] ath9k: introduce bus specific DMA routines
-
-In the AR913x SoCs, the WMAC devices are connected to the CPU through
-the internal AHB bus instead of PCI. We first patch ath9k driver to use
-replaceable DMA routines, so we can use different code for the AHB bus.
